---MINIMAGE---This app brings to iOS the possibility to experiment with a large variety of image-processing operations. In interactive mode, it works like a calculator that operates on images. It also comes with a scripting language that facilitates the prototyping of algorithms. A large body of documentation is available directly from the app.---INTENDED AUDIENCE---Minimage is designed to help engineers and students understand, experiment, and develop algorithms. It is focused on the mathematics behind image processing and is intended more for the technically savvy than for the general user.If you want to develop a new algorithm while on-the-go, this app is for you. Your development will benefit from a powerful scripting language that contains all that is needed (e.g., access to pixels, tests, loops, recursions, handling of variables, user interaction, debugging). Many script examples are provided to get you started with the language, which is Forth-like. Every element of the language is documented; no network access is required to consult this documentation or to operate the app.---WHAT IT DOES---• Strict adherence to the mathematical description of operations• Access to classical color/grayscale images and to the photo album• Linear and morphological filters, with arbitrary kernels• Many point-wise functions, many operations between images• Uniform and Gaussian noise, Fourier transform• Geometric operations• Close inspection of pixel values and statistics• Unlimited undo/redo• Contextual help, along with a comprehensive index• Interactive mode and scripting mode---WHAT IT DOES NOT DO---• Photo embellishment• Acceleration tricks• Regions of interest---IT IS FREE AND COMPLETE---This app is free. There are no ad nor in-app purchases, and this is not a crippleware.
